GAS-LAMP.

Specification of Letters Patent.

Patented May 21, 1907.

Application filed December 5, 1906. Serial No. 346,3 84.

To a whom, (It may concern.-

Be it known that I, RUDOLPH E. BRUCK- NER, a citizen of the United States, residing at Mount Vernon, VVestchester county, New York, have invented certain new and useful Improvements in Gas-Lamps, of which the following is a full, clear, and exact descriptlon.

My invention relates to improvements in gas lamps. I

It has particular utility in connection with lamps used for railway purposes.

The object is to prevent smoking or sooting of the reflector.

Figure 1 is avertical section of a car lamp of conventional form, Fig. 2 is a relatively enlarged section of a portion of said lamp taken on a different plane from that of Fig. 1

Fig. 3 is a side elevation of a head light, Fig.

4 is a cross-section thereof.

I will describe first the construction shown in Figs. 1 and 2. In said figures, A represents the main frame of the lamp proper, the same being suspended by arms B B, one of which may be a gas supply pipe provided with a valve O. D is a continuation of the pipe B within the lamp proper. E E are burner heads. F is a transparent bowl-like globe extending under the pipe D and burners E E. The bowl F is suitably suspended from the frame ring A. G is an over-head reflector, preferably of white porcelain-like material. H is a crown, so called, supported by the part G, the latter being supported by the ring A. The part A is perforated at intervals, one of said preforations being indicated at I, Fig. 2. Air is permitted to enter through the ornamental shell J and pass through the perforations I into the interior of the lamp to supply oxygen to the flame. K

is a deflector located in front of the openings I and arranged to deflect the air to enter the lamp so that it will sweep down the sides of the bowl E, as indicated, by arrows, in Fig. 1. L is a tube-like hood of suitable transparent material hung from the crown II and overstanding the burners E E, though terminating considerably above the same. Part of the air entering the sides of the lamp and passing the deflector I will, instead of passing to the flame, pass directly to the tubular hood L and form an annular air envelop into the center or vortex of which the hot gas arising from the flame will flow in such a manner as to eliminate any danger of the products of combustion being condensed or deposited upon the reflector G.

I have demonstrated by practical experiments that the effectiveness of the air envelop at the entrance to the hood L is such as to prevent the spreading of the gases. In fact, in actual practice, the effect of the air envelop is to make the lower edge of the hood L (although directly above the flame) comparatively cool.

In Figs. 3 and 4, I have shown the same invention applied to a locomotive headlight,wherein the preservation of the reflector is of the utmost importance. In this view, K represents the deflector, G the reflector, L the hood, E the burner. Air enters through the passage I indicated in dotted lines, thence past the deflector K and thence freely into the space within the reflector G. The lower end of the hood L, as shown in dotted lines, extends below the reflector and over the burner E, stopping above the same. In this case the air envelop is formed around the lower edge of the tubular hood L, as in the first instance, and the products of combustion are drawn into the vortex and conducted upwardly and discharged through the crown H.

The construction not only prevents the deposit of products of combustion upon the flame reflector, but the air envelop entering the hood protects the side walls of the same against the deposit of said products therein, since the said hood L is preferably of transparent material (although it might be translucent), there is no substantial resistance to the rays of light from the burner to all parts of the overhead reflector. I have found mica to be a very effective material from which to make the tubular hoods L.

What I claim is:

1. In a lamp of the character described, a gas burner, a translucent inclosure therefor including a centrally perforated reflector above the same, a tubular hood entirely above the burner, the lower edge of the hood projecting below the reflector, and admission ports at the sides of said burner inclosure and a deflector in front of said ports directing the air up and down within said inclosure.

2. In a lamp of the characterdescribed, a

gas burner, a centrally perforated reflector above the same, a transparent tubular hood entirely above the burner, the lower edge of the hood projecting below the reflector, air supply ports at the sides of the lamp and below said reflector and a deflector in front of said ports.

3. In a lamp of the character described, a gas burner, a closure therefor comprising a transparent lower bowl, a reflecting dome, air supply inlets at the sides of said closure, an air outlet through said dome, a substantially transparent hood projecting into said closure terminating above the burner and supported entirely from above, a deflector arranged to direct some of the air entering at the sides upwardly and some downwardly.

4. I11 a lamp of the character described, a gas burner, a reflector above the same and forming a dome open at the center, a substantially transparent tubular hood projecting below the dome terminating above the burner and suspending entirely from above, air admission ports at the sides, and a deflector in front of said ports to direct some of the air entering the lamp upwardly and some downwardly, and a transparent bowl closing in the burner between it and said dome.

5. In a lamp of the character described, a gas burner, a translucent closure therefor, an air admission port at the side thereof, and a baffling device for said port externally of said closure, a second baffling or deflecting device located within said inclosure and in front of said air port and arranged to deflect air up and down within the closure, and a trans-v parent tubular outlet hood suspended from above projecting below the deflector and terminating above the burner.

6. In a gas lamp, a gas burner, an inclosure therefor, a deflector within said inclosure and overstanding an air admission port therein, a reflector wall above the burner, a translucent tubular hood overstanding said burner and terminating above the same, said hood projecting downwardly 1n the reflector and extending below the adjacent wall thereof.
